Hello, 1) I have not yet understand what is a category in xWiki and how to fill it (I succeed to create mine, but I can't put anything into it). 2) In fact, I looking for a category as mediawiki. For instance, my xwiki is a presentation of books. So when I see the book main page, I will have the text and the list of the subcategories (book of mathematics, book of physics, ...). When I add a new sub category (like books on computer sciences), I would like that it will be automatically add to the book main page. And I will also that this page shows to the user the subcategory like : documentation about compiler, and documentation about wiki. And in the page about wiki, I would like to have a list of hyperlink to page that describes mediawiki, xwiki, ..... Are this kind of mechanism fully , partilly coded into xwiki ? If not how to code it ? Thanks, PHL. -- View this message in context: http://www.nabble.com/Category-%28and-hierarchical-category%29.-tf3704021.ht...
